I think that Carol said that she had already been to Egypt
and wants to visit Israel this time. You can take a bus
direct from Jerusalem/Tel Aviv to Cairo. You can also cross
the land border into Jordan in 5 places (not by direct bus).
There is one tour company, Masada that will provide direct
transportation via the Sheik Hussein bridge. (Private tours)

To visit Petra, the Eilat-Aqaba crossing is probably easiest.
